Cold-rolled ribbed steel structure design points: The minimum reinforcement ratio selection. The use of reinforced concrete structure in the longitudinal flexural members by pulling the minimum reinforcement ratio CRB550 cold rolled steel rebar plant, take O. 2% and 45ft / fy%, whichever is greater, when using C35 concrete after the entry of 0.196%. Cold-rolled steel in other words, when the concrete strength class C35 and below. The minimum reinforcement ratio is from 0.2% to control CRB550 cold rolled rebar, rebar can not be blind and other strong substitution. Cold-rolled ribbed steel structure design elements: other construction requirements. Plate, with reinforced walls minimum spacing maximum and minimum diameters of the reinforced concrete slab bottom reinforcement force of not less than 6mm CRB550 cold-rolled steel prices, the Ministry of board configurations negative moment reinforcement diameter of not less than 8ram, the reinforced and The maximum distance between the distribution of tendons and exposed roof structure is generally not more than 200ram; minimum diameter distribution of steel not less than 5mm, the maximum spacing should not exceed 250ram. CRB550 cold rolled steel manufacturers, cold-rolled steel, cold rolled by Ding Ding Ding Ding Industrial Co., Ltd., Henan Province.
